COMMAND USAGE
◆ The re-authentication process verifies the connected client’s user ID
and password on the RADIUS server. During re-authentication, the
client remains connected the network and the process is handled
transparently by the dot1x client software. Only if re-authentication
fails is the port blocked.
â—† The connected client is re-authenticated after the interval specified by
the dot1x timeout re-authperiod command. The default is 3600
seconds.

Console(config)#interface eth 1/2
